The Technology Behind Your Companions
Nexani companions are powered by advanced large language models (LLMs) fine-tuned for natural, engaging conversation. Here is what makes them special.
Memory System
Each companion maintains a persistent memory of your conversations. They remember your name, preferences, past topics, and inside jokes. This memory grows over time, making each companion uniquely yours.
Personality Engine
When you create a companion, your personality settings are translated into behavioral guidelines the AI follows during every response. The engine considers traits like humor level, empathy, formality, and creativity to produce consistent characterization.
Context Window
Each message you send is processed alongside recent conversation history, your companion's personality, and key memories. This context window is what allows the AI to maintain coherent, on-topic discussions across long conversations.
Image and Voice Generation
Image generation uses a separate diffusion model that takes text descriptions and produces visuals in seconds. Voice synthesis converts your companion's text responses into natural-sounding audio. Both features cost tokens to use.
Continuous Improvement
We regularly update our AI models to improve conversation quality, reduce errors, and add new capabilities. Your conversations are never used to train models - your privacy comes first.
